Preheat the oven to 350°F (177°C). Line a baking sheet with parchment paper to prevent sticking.
02 -
Combine butter and half of the chocolate chips in a microwave-safe bowl. Heat in short bursts, stirring until smooth. Allow to cool to prevent scrambling eggs in later steps.
03 -
Whisk granulated sugar, brown sugar, eggs, and vanilla extract in a large bowl until mixture is smooth and glossy.
04 -
Pour the cooled melted chocolate mixture into the sugar and egg mixture. Stir gently until just combined, maintaining tenderness.
05 -
Sift flour, cocoa powder, baking powder, and salt together. Fold into the wet mixture carefully until no streaks remain.
06 -
Refrigerate the dough for 15 minutes to firm up, helping to control spreading during baking.
07 -
Scoop dough into mounds. Press a few reserved chocolate chips into the center of each mound before sealing the cookie dough around them. Place on the prepared baking sheet spaced apart.
08 -
Bake for 10 to 12 minutes until tops are glossy and cracked but centers remain soft to achieve the molten lava effect.
09 -
Allow cookies to rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool without steaming their bottoms. Serve warm for optimal molten center.
